What is The Differences Between LSAW Pipe and SSAW Pipe

Differently SSAW pipe is spiral welded where the LSAW is longitudinally welded. Manufacturing process is rolling the steel strip, to make the rolling direction have an angle with the direction of the pipe center, forming and welding, so the welding seam is in a spiral line.

The SSAW steel pipe is made utilizing hot rolled steel strip which is spiraled at room temperature level to be bonded. Automatic immersed arc welding is the most commonly utilized technique in the spiral tube production, and the end items come with welding joint both inside and outside.

Difference between ERW, SSAW, LSAW - Sunny Steel

Steel pipe for pipe technology, can be divided into (SML), mainly as the Oilfield internal transportation pipeline and small-diameter high-pressure natural gas pipeline, used for a small number of long-distance gas pipeline, the vast majority of long-distance pipeline with Direct seam high frequency (ERW), spiral submerged arc (SSAW), LSAW three (LSAW).

Welded Pipes (ERW, LSAW, SSAW) – DANYAL PIPELINES

ERW Steel Pipe-Electric Resistance Welded Steel Pipe is made of hot-rolled steel coils/sheets that have been put in a process known as cold roll forming. The obvious advantage of ERW steel pipe compared to seamless steel pipe is the uniform wall thickness.

Difference between ERW Pipes, SSAW Pipes and LSAW Pipes ...

Spiral submerged arc welded (SSAW) pipes has spiral welding joints and the pipes are welded and formed at the same time. The strip steel with the same specification can produce SSAW pipes with various diameters. The welding joints can avoid major stress and have better force resistance.
